Basically the reaction conditions found for preparation of strontium L-glutamate (Example 8) was employed. A suspension of L-glutamic acid (white coloured) is prepared by adding 100 mL of millipore water to 14.713 g (0.1 moles) of solid L-glutamic acid (FLUKA 49449, MW 147.13, CAS 56-86-0) in a 250 mL beaker. To this suspension was added 37.86 g (0.12 moles) of solid barium hydroxide octa hydrate (FLUKA 11780, Ba (OH)2*8H2O, MW 315.5, CAS 12230-71-6). The reaction procedure described in Example 8 was followed.
